oh huni i feel your pain i really do. My ex had the same prob.Altho we did not meet on one he was addicted to them.I had had th sit down chats and told him how i felt when i seen them more so how i felt when reading the things he sent to others on there too. He also after the first time would denie it..............right down to trying to tell me the one that was being paid for with his credit card was an issue of identity theft.

To me it is cheating as well the way i see it is clear cut and simple.......If you wouldnt do it with your partner sitting beside you then you know its wrong and is cheating. The fact he has to hide it shows he knows he shouldnt be doing it. I put up with it for years and it progressed from him telling me he only did it as he was bored to me finding out that he was in fact having phone relations with some of the women on there.

I cant tell you what is the right thing to do,just follow your heart hun.Try and sit with him and let him know again how it makes you feel and that you dont like it,and that he needs to respect that. Lay it out for him and like PZ said he will either realise and man up or you will walk.

HUGS to you hun i do hope things turn out for the best for you
